Exposure Modeling

Predicting pesticide concentrations in the environment

Assessments of a potential exposure of ground water, of populations in ground or surface waters or in terrestrial ecosystems are based on different computer models simulating the fate of plant protection products in the environment. Fraunhofer IME has been involved in the development of some of these models.

We are also experienced in evaluating own or external studies according to FOCUS (2006) and EFSA (2010), e.g.:

- Assessment of degradation studies in the laboratory (soil, water/sediment) using non-linear adaptation models considering recommended kinetics: Single First Order (SFO), First Order Multi Compartment (FOMC), Double First Order in Parallel (DFOP) and Hockey Stick (HS)

- Evaluation of outdoor degradation studies according to the requirements of EFSA (2010)
